Under these circumstances, it is normally not necessary . process test, the acceptance criteria should remain part .
The measured tablet hardness value is compared against pre-established tablet hardness test acceptance criteria or specifications. These criteria are determined during the tablet formulation and development stage . Generally, the microbial content test should not be required for most of the tablets except vitamin tablets, and sugar-containing tablets. It is a crucial pharmacopoeial test for the evaluation of tablets or quality control tests of tablets. Acceptance Criteria for Microbiological Quality of Nonsterile Dosage Forms [2]

Only QW-290 for temper bead welding defines hardness testing. Hardness testing of carbon steels are not defined in most construction Codes; it is addressed in API-582 and various NACE publications as a means to mitigate stress corrosion cracking. ASME Codes place the responsibility for corrosion related design on the Owner/Engineer.
The Vickers hardness test is ideal for testing of all metals and is therefore the method with the widest range of application. The hardness test method according to Vickers is described in standards ISO 6507 (Metallic materials – Vickers hardness test – Part 1: Test method) and ASTM E384 (Standard Test Method for Microindentation Hardness (1gf - 200 gf) of Materials .
If a testing machine is also to be used for other methods of hardness testing, it shall be verified independently for each method. This part of ISO 6508 is applicable to portable hardness testing machines. 2 Normative references The following referenced documents are indispensable for the application of this document. For datedThe Vickers hardness testing method offers advantages such as a small indentation size, accurate hardness measurements, and applicability to a wide range of materials. Series measurements or mappings are very often carried out using this met-hod. However, it may not be suitable for very soft or highly textured materials, while alternative .These are tests that are performed on tablets and which are not listed in official compendia and concern a variety of quality attributes that need to be evaluated, such as the porosity of tablets, hardness or crushing strength test, friability test, tensile .
i SPECIFICATIONS: TEST PROCEDURES AND ACCEPTANCE CRITERIA FOR NEW DRUG SUBSTANCES AND NEW DRUG PRODUCTS: CHEMICAL SUBSTANCES ICH Harmonised Tripartite Guideline Having reached Step 4 of the ICH Process at the ICH Steering Committee meeting on 6 October 1999, this guideline is recommended for adoption to the three regulatory . I recommend you purchase and review ASTM D2240, Standard Test Method for Rubber Property—Durometer Hardness.Section 7 explains the methodology for calibrating rubber durometers of all types. You can buy sets of Rubber Test Blocks, but I recommend using them only for quick checks because the Type A durometer leaves indentations in the blocks that . Can anyone explain about the Acceptance criteria of Hardness for the weld metal. If my PQR is as per ASME SEC IX and if the hardness test is done, on what basis the test results are acceptable. Also please explain the same .acceptance criteria established for the periodic test should be handled by proper notification of the appropriate regulatory authority(ies). If these data demonstrate a need to restore routine testing, then batch by batch release testing should be reinstated. 2.2. Release vs. shelf-life acceptance criteria
Hardness testing surveys are as described in NACE MR0103. In addition to the ASME IX requirements, SP0472 requires butt welds and fillet welds to be qualified separately; although not mandatory, it would also be advisable to qualify .
Vickers Hardness Testing: Utilises an optical measuring system to measure the area of the impression; Knoop Hardness Testing: Employs a diamond penetrator to impress a sample; Shore Hardness Testing: Uses the principle of measuring the resistance of a material to indentation; Advanced Techniques in Hardness Testing Methods
The Brinell hardness HBW results from the quotient of the applied test force F (in newtons N) and the surface area of the residual indentation on the specimen (the projection of the indentation) after removal of the test force (see Brinell formula).To calculate the surface area of the residual ball indentation, the arithmetic mean d of the two perpendicular diagonals d1 and d2 (in mm) is .Tests, frequency and acceptance criteria in testing of material for structures as per quality assurance level Q-4 of IRC: SP47-1998 and other IRC, and MORTH. . Hardness no IS:1195-1978: In situ: In situ: 60-80 at 25ºC before addition of C.A. and 10-20 at . The Brinell hardness test identifies the indentation hardness of a desired material. Guidelines for Brinell testing machines and the procedures for performing Brinell hardness tests are standardized through ASTM E10-23: Standard Test Method for Brinell Hardness of Metallic Materials.

Results are to be documented. Hardness Testing Brinell and/or Rockwell hardness testing is to be performed in accordance with ASTM E10, ASTM E110,
Although there is not definite number for the hardness of the tablet, there is a recommended range which is most likely sufficient for handling, this is between 1.5-4 MPa or approx 15-40 Newton.
As illustrated in Fig.3(b) two diagonals, d 1 and d 2, are measured, averaged and the surface area calculated then divided into the load applied.As with the Brinell test the diagonal measurement is converted to a hardness figure by referring to a set of tables. The hardness may be reported as Vickers Hardness number (VHN), Diamond Pyramid Number (DPN) or, most commonly, Hv .Supplementary Specification to API Specification 5L and ISO 3183 Line Pipe Page 1 of 151 S-616 November 2020 Foreword This specification was prepared under Joint Industry Programme 33 (JIP33) "Standardization of Equipment
Neither D1.1 nor ASME IX require hardness testing, except for hardfacing overlay or temper bead welding under IX. Where did your acceptance range come from? I suspect it could be a customer requirement, which is up to the customer to accept or reject. The PQR is still valid for welds not subject to hardness testing qualifications.
